All gas tanks by W&W Cycles are delivered unpainted and unsealed. Before the paint job and final installation please consider the following:

  • We consistently receive tight gas tanks from the manufacturers, both Custom and OEM replacements.
  • Problems mostly occur during or after installation. Hence, BEFORE a pressure test and BEFORE painting - a probationary (STRESS-FREE!) installation is highly recommended. Any leverage on the tank mounts spells trouble. Better use our selection of small parts.
  • To avoid corrosion always fill your tank to the max during longer downtimes or seal it on the inside.
